Hard on the heels of Linux’s 17th birthday came two more notable milestones for the operating system, both of which came to light in the past week. First, the Linux kernel surpassed 10 million lines of code — albeit with blank lines, comments and text files included. A full 96.4 percent of that code is written in C, while 3.3 percent is written in Assembler, according to the Heise article that reported the news, attributing the counts to the SLOCCount tool.
